Take 3/8 inch fan fold foam insulation <homogeneous 2 lb blown
strofoam><br>
in 4 ft by 50 ft packs and using 1x4 wood trim cut to ~24 inches nail
through<br>
the 1x4 oriented vertically to pin the foam against the wall.... just
make sure<br>
you miss the stud placements...<br>
<br>
Preferably use 4 ft x 8 ft sheets of 1 inch Blue Board foam, 1x4
horizontal<br>
at top and bottom, for trim backing and vertically every 24 inches, and
skip the<br>
steel studs and the fiberglass. I've done this several times with
concrete block.<br>
Use cut nails 10p. I've never seen moisture problems with blue board but<br>
have seen rot with below grade fglass batts......<br>
